SGM2529
5A, 5V Electronic Fuse (eFuse)
with Thermal Shutdown
GENERAL DESCRIPTION
FEATURES
The SGM2529 is a compact electronic fuse (eFuse)
with a complete set of protection functions. The
SGM2529 provides excellent accuracy, making it very
suitable for many system protection applications.
● 5V Electronic Fuse with Surge up to 30V
● Extremely Low RDS(ON) for the Integrated
Protection Switch: 26mΩ (TYP)
● 3-State ENABLE/FAULT Pin, Bidirectional Interface
● Programmable Soft-Start Time
It provides accurate over-voltage (OV) and under-
voltage lockout (UVLO) protections, which ensure tight
supervision of bus voltages and eliminate the need for
supervisor circuits. The over-voltage (OV) protection
will clamp the eFuse output at a fixed level during input
voltage surges. During the input voltage transient, the
internal FET remains on, which allows the load to
continue to operate. If the transient duration remains
long, the accumulated heat will cause the eFuse
thermal shutdown. Once in thermal shutdown, latch-off
and auto-retry thermal options are available.
● Programmable Current Limit up to 5A
● Thermal Shutdown Options:
SGM2529A: Thermal Latch-Off with VCLAMP
SGM2529B: Thermal Auto-Retry with VCLAMP
SGM2529C: Thermal Latch-Off without VCLAMP
● Fault Output for Thermal Shutdown
● Accurate Under-Voltage Lockout
● Accurate Over-Voltage Clamp (SGM2529A and
SGM2529B)
● Available in a Green TDFN-3×3-10L Package
The SGM2529 is available in a Green TDFN-3×3-10L
package.
